Hey #Java #Emacs users, I am trying to smoothen my workflow. One thing that annoys me is to go to mvnrepository.com to look up a package. I am creating a little helper for it, anyone interested?

I gave my workshop at #jfall2025 #jfall today. It was a success, a packed room and people working through my AI challenges for 2 hours. If you attended you might like the slides, they are available on my talks page: arjenwiersma.nl/talks/

Just finished up my workshop at #jfall #jfall2025! Great crowd and lots of interaction, even in the silent disco setup!

I made an update to my #emacs upiv package from yesterday, it now supports marginalia mode for even nicer support with configuring use-package. URL: forge.arjenwiersma.nl/arjen/upiv

I so love my #emacs, was configuring some packages and wanted something easier, so I wrote a small function that will look up all the custom variables for a package and provide them as completion, allowing you to easily insert them. Trying to be more like @xenodium.bsky.social by sharing.

During my talk at #devoxx I talked about how big systems leak data through bad #ai implementations, this morning I read about copilot for GitHub: www.legitsecurity.com/blog/camolea... it never stops…

Ranking of different types of developers #vibecoding #devoxx #useyourbrain

Had an amazing time presenting at #Devoxx! The room was packed, with some people sitting on the stairs, if the favorites are anything to go by there were over 300 people in the room. The talk was rated 4.7 out of 5, which for me is amazing, thank you all so much!

My talk at #Devoxx is up to 69 ❤️! Nice! Hope to see you all on Wednesday!

Love this article on a new industry; cleaning up vibe coded projects donado.co/en/articles/...

Hey you Java person! Are you going to @devoxx.com ? Be sure to visit my talk on the security side of vibe-coding. Check it out in the app: www.devoxx.be/app/talk/325...

In april Microsoft said 30% of their code was written by AI, coinbase is pushing even further with 40% and aiming for 50% by October. Massive numbers, but still in a controlled way (reviewed)

Tonight I will be presenting at the #DevPulse meetup in the city of Zwolle. See you there!

📅 The wait is over: the #Devoxx Belgium 2025 schedule is out! Plan your week, pick your favourites ❤️https://m.devoxx.com/events/dvbe25/schedule

Rest well, Ozzy. Everyone listen to Tribute in his honor today. music.apple.com/us/album/tri...

Just posted my first of 12(!) parts on AI Security. A bite-sized deep-dive into AI security delivered right into your mailbox from my substack. Check it out: credmp.substack.com

For me #clojure is like stoic philosophy, leading a simple and humble life in the #repl.

EU ruling: tracking-based advertising across Europe has no legal basis. A massive ruling that is effective right away, means that organisations that rely heavily on advertisement (such as dpg/nu.nl in the Netherlands) will have to review and adjust their practices. www.iccl.ie/digital-data...

Remember how Microsoft said it would go to court to protect European interests if faced with American orders to work against it? Seems it was not entirely true: www.techradar.com/pro/microsof... www.pbs.org/newshour/wor... “Microsoft, for example, cancelled Khan’s email address”.

Every once in a while I try different knowledge management systems, recently I have been using #logseq, but I always come back to the simplicity of my #emacs setup with org-roam…

Went shopping for comics today, completed my 1-100 series for Spawn and added a good chunk for 100-200. Kinda feels like Christmas. #comics #spawn

Today I was at the futuretech conference in Utrecht. Really liked @fonssonnemans.bsky.social talk about performance analysis.

Using @openvibe.social feels to me like using eBuddy back when there were a lot of instant messaging apps. Everything neatly in a single space, one user experience. Very nice so far.

Do we know anyone at @digitalocean.com here? Their app platform has a provisioning issue that renders postgres 16 dev databases useless and their support is not particularly helpful. Any help in my network is appreciated! #digitalocean #postgresql

Hey it'd be super cool if you reposted this post to let all your cool friends know that @slashdot.org is on Bluesky now!

Day 15 of #adventofcode was quite a puzzler. Rewrote my solution several times. I take solace in the fact that the fastest solvers needed 15 minutes, which means the problem was hard. My notes on my #Java solution are here: arjenwiersma.nl/posts/aoc-20...

My #adventofcode in #java notes for Day 14 are up. This day has some math with modulo for wrapping around grids, also, Java module does things with negative numbers. Check out the notes here: arjenwiersma.nl/posts/aoc-20...

My notes on day 13 of #adventofcode in #java are up. Today I used math to solve the problem: arjenwiersma.nl/posts/aoc-20...

My notes on #adventofcode in #java for Day 12 are up! Had quite some work with finding a nice way to count the sides, so instead I counted corners. Check it out: arjenwiersma.nl/posts/aoc-20...

Day 11 of the #adventofcode was one to remember. My notes on attacking this problem in #java are here: arjenwiersma.nl/posts/aoc-20...

#adventofcode is not disappointing this year! Had great fun on Day 9 and Day 10. My notes on doing the puzzles in #java are up: arjenwiersma.nl/posts/aoc-20... . For those curious, my Day 9 part 2 runs in less then 50ms :D. Now it is time to watch the videos from #emacsconf, thanks @sachachua.com !

Jammer om te zien hoe (relatief) slecht onze @ns.nl scoort in vergelijking met andere Europese diensten: www.transportenvironment.org/articles/rai...

Day 8 of #adventofcode in #java is solved! I wrote my notes on my running blog article: arjenwiersma.nl/posts/aoc-20...

Sad to read that Nicko is retiring, much love to his drumming skills. Up the irons, Nicko! Loved all 14 live shows I visited. www.ironmaiden.com/an-announcem...

My notes on #adventofcode day 6 and 7 in #java are up! Check them here: arjenwiersma.nl/posts/aoc-20...

I just completed "Bridge Repair" - Day 7 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/7, compared to yesterday it was a breeze, just a good case of recursion :D

#adventofcode today left me with only a bruteforcing option. Doesn't feel right, but it solves. #java

Solving part 2 of day 5 from the #adventofcode turned out to be surprisingly easy using #java Comparator classes. Just a custom sort function to save the day! My notes on the day are here: arjenwiersma.nl/posts/aoc-20...

Day 4 of #adventofcode was a lot of fun again. I quickly stepped into the "lets do some pathfinding" pitfall to only step back to basic array operations for part 2. My notes on the implementation in #Java are here: arjenwiersma.nl/posts/aoc-20...

When I professionally started programming it was in #Perl and I worked on a log parsing system. It had the most convoluted regular expressions around.... and in Day 3 of the #adventofcode I had a use for that knowledge, once again! Using regexes made this problem easy.

In day 2 of #adventofcode you might want to splice an array and then combine it again, in #Java you can use an IntStream to seamlessly remove a single element from an array. #tipoftheday

Day 1 of #adventofcode was a great starter again. I tried to write it using streams as much as possible, and it worked out very nicely!

Almost time for #adventofcode... Spent last night dusting off some Dynamic Programming notes. No use of #ai for the challenges, just my old #brain.

Love how modern #java enables rapid creation of apps. Spent a few hours this morning building an #ai tool using #springboot and #htmx. Ready for production.
